using xpath simple xml with google contacts api?

I'm using google contacts api and php to parse an xml like so: 

$req = new Google_HttpRequest("https://www.google.com/m8/feeds/contacts/default/full");
$val = $client->getIo()->authenticatedRequest($req);
$xml = simplexml_load_string($val->getResponseBody());
$xml->registerXPathNamespace('gd', 'http://schemas.google.com/g/2005');

  $output_array = array();
  foreach ($xml->entry as $entry) {
    foreach ($entry->xpath('gd:email') as $email) {
      $output_array[] = array(
        (string)$entry->title, 
        //THIS DOESNT WORK WHY??
        (string)$entry->attributes()->href, 
        //
       (string)$email->attributes()->address);

    }
  }

This returns:

[1]=>
  array(3) {
    [0]=>
    string(14) "LOREM IPSUM"
    [1]=>
    string(0) ""
    [2]=>
    string(28) "[email protected]"
  }

the raw xml response is like so: 

     <entry>
      <id>http://www.google.com/m8/feeds/contacts/EMAIL/base/e29c818b038d9a</id>
      <updated>2012-08-28T21:52:20.909Z</updated>
      <category scheme="http://schemas.google.com/g/2005#kind" term="http://schemas.google.com/contact/2008#contact" />
      <title type="text">Lorem ipsum</title>
      <link rel="http://schemas.google.com/contacts/2008/rel#edit-photo" type="image/*" href="https://www.google.com/m8/feeds/photos/media/EMAIL/e29c818b038d9a/1B2M2Y8AsgTpgAmY7PhCfg" />
      <link rel="self" type="application/atom+xml" href="https://www.google.com/m8/feeds/contacts/EMAIL/full/e29c818b038d9a" />
      <link rel="edit" type="application/atom+xml" href="https://www.google.com/m8/feeds/contacts/EMAIL/full/e29c818b038d9a/1346190740909001" />
      <gd:email rel="http://schemas.google.com/g/2005#other" address="[email protected]" primary="true" />
   </entry>

How do i get at the image url aswell as the contact name and title?

You are attempting to access the <link> elements, but are accessing the attributes() of $entry, which does not have href attributes.

// Doesn't have an href attribute...
(string)$entry->attributes()->href

Instead, get the link elements and loop over them to create an array of href.

  $output_array = array();
  foreach ($xml->entry as $entry) {
    // Initialize an array out here.
    $entry_array = array();

    // Get the title and link attributes (link as an array)
    $entry_array['title'] = (string)$entry->title;

    $entry_array['hrefs'] = array();
    foreach($entry->link as $link) {
      // append each href in a loop
      $entry_array['hrefs'][] = $link->attributes()->href;
    }

    // If there are never more than 1 email, you don't need a loop here.
    foreach ($entry->xpath('gd:email') as $email) {
      // Get the email
      $entry_array['email'] = (string)$email->attributes()->address
    }
    // Append your array to the larger output
    $output_array[] = $entry_array;
  }

  // Look at the result
  print_r($output_array);
